KNOUKDOWN SHIPPING TUBE.

Application filed. March 25, 1922. Serial No. 546,820.

To all whom it may concern: tudinal sectional view of one end of the Be it known that I, VVILLIAM J. Hannshipping tube in its set up position.

and useful Improvements in a Knockdown In carrying out my invention as here em- Shipping Tube, of which the following is bodied, i and 5 represent two semi-tubular a specification. members formed of any suitable material My invention relates to new and useful in any well known or preferred manner improvements in a knockdown shipping although here shown as built up of a num- 65 tube, and has for its object to provide a ber of spirally wound layers n the same device of this character for shipping rolls manner as the well known mail ng tube is of paper, linoleum, rugs and the like so as made. In actual practice a tube is first prot t t h ti l ag i t dama e and duced and then split longitudinally to proprevent the ends from being torn, cracked d c the tWO m mb rs. 70 or bent. On the inside of each of the semitubu Another object of the invention is to prolar members at or adjacent their ends are vide a shipping tube of the class stated located the semi-circular flanges 6 thereby which may be collapsed and the parts nested forming shoulders 7 a short distance inside in one another when empty so as to occupy or short of the ends.

40 In order that those skilled in the art to As these shipping tubes are preferably which this invention appertains, may undermade of card board or like material they stand how to make and use the same. I will have a. certain amount of resiliency or flexidescribe its construction in detail, referring bility so that one semi-tubular member may by numerals to the accompanying drawings be nested within another by slightly expand- '15 forming a part of this application, in ing one and compressing another as will be which readily understood. When the two members Fig. 1, is a perspective view of a knockare nested as shown in Fig. 5 they occupy down shipping tube embodying my invenless space than when in a set up position, as tion. shown in Fig. l, and when in this condition 50 Fig. 2, is an enlarged section at the line may be returned to the shipper at small ex- 22 of Fig. 1, looking in the direction of pense.

the arrows. a When packing an article or object in one Fig. 3, IS a similar View at the line 3-3 of the shipping tubes one of the semi-tubular of Fig. 1. members may be laid upon a suitable sup Fig. 4, is an enlarged fragmentary longiporting surface, such as a floor of a building,

and the article or object placed therein either before or after the caps 8 have been set in place. The other semi-tubular member is then placed over the article and positioned so that the caps S are inside of the flanges of said member which will permit the longitudinal edges of said members to contact with one another. Next the ties or bales 9 are placed about the completed tube and drawn taut so as to rigidly hold the parts in place. i

As an example for illustrating the advantages of a shipping tube constructed in this manner I will presume that a roll of high grade or expensive paper is the article or object contained in the tube. The workmen handling this class ofgoods will often up end the roll causing the edge'of the paper to be mashed, torn or otherwise damaged so that the purchaser is compelled to cut otias waste a strip of considerable width and length along both edges'so that a considerable .part of the paper will not then cut up into uniform sized sheets producing an enormous loss to large users of this class of paper. Further under present-day methods such a roll of paper is wrapped with many layers of wrappings of a cheaper grade pa.- per which is a complete loss to both the shipper and purchaser.

These are disadvantages which are entirely orpartially eliminated by the use of my device because the tube being of very stilt material the ends are unlikely to be mashed ordamag'ed and even thoughthe ends of the the exact details of construction as herein shown as these may be varied within the limits of theappended claims without departing from the spirit of my invention.

Having thus tully described my invention, what I claim as 'new 'and'useful 1. In a device of the character statechtwo r separate semi-tubular members adapted 'to be nested one within another b1 "set up to form a tube, means for holding said memhere in a set up position, semi-circular internal flanges located at each end of each member, and caps fitting within the tube formed. from the aforementioned members and contacting withthe inner portions of the flanges by which said caps are prevented from outward displacement.

2. In a device at the character stated a pair of separate semi-tubular members, a scmi-circularflange at each-end'ot each member, said members adapted to be telescoped or nested one within the other or set up in opposed relation to produce a tube, caps within the tube thus formed, said caps being held against outward displacement by the flanges, and ties secured about'the completed tube for holding *the parts in place.

In testimony whereof, I have "hereunto at fixed my signature.
